Question about burning of humid wood:

How much heat (in Megajoules) can you generate from 1 kg of humid wood which has a temperature of 5 degrees celsius?

To determine the moisture content of the wood, some pieces of humid firewood was put in an oven weighing 100g each.

The temeperature of the oven is 100 degrees celsius, and after all the moisture evaporated, the dry pieces of firewood weighed 85g each.

The heat capacity for humid wood is approximated to 1.8 KJ/kgK. To answer this question you need to calculate the LHV for wood at 25 degrees celsius first.
